Optical Channel Performance Monitor In IntelliGuardTM OCPM Series
BaySpec’s OCPM Series Optical Channel Performance Monitor is an embedded, integrated spectrum analyzer delivering precise measurement and powerful processing capabilities for dense wavelength division multiplexing (DWDM) applications. The device covers C and L band wavelength ranges and provides simultaneous measurements of up to 160 channels spaced 50 GHz apart. High reliability (GR63/1209/1221 qualified) is achieved through a rugged mechanical design with no moving parts. Periodic calibration is not required. Input/Output (I/O) is provided through a dual port RAM interface accessed through ADD/DAT bus direct connection or serial (RS232 or USB) communications. The IntelliGuardTM OCPM Series employs a highly efficient Volume Phase Grating (VPG®) as the spectral dispersion element and an ultra sensitive InGaAs array detector as the detection element, thereby providing high-speed parallel processing and continuous spectrum measurements. As an input, the device uses a tapped signal from the main data transmission link through a single mode fiber, then collimating it with a micro lens. The signal is spectrally dispersed with the VPG®, and the diffracted field is focused onto an InGaAs array detector. The control electronics read out the processed digital signal to extract required information. Both the raw data and the processed data are available to the host through the chosen interface.
